Abstract

The utility model discloses a groove position measuring instrument, which comprises a V-shaped block, a dial indicator, an indicator base, a connecting rod, a compressing rod, a compressing head and a standard component. The left lateral surface of the V-shaped block is provided with a longitudinal dovetail groove, while the rear end face thereof is provided with a transverse dovetail groove. The indicator base is in sliding connection with the longitudinal dovetail groove of the V-shaped block. The dial indicator is fixed on the indicator base and is vertical to the left end face of the V-shaped block. The connecting rod is in sliding connection with the transverse dovetail groove of the V-shaped block. The compressing rod is fixed at the upper end of the connecting rod and is vertical to the rear end face of the V-shaped block. The compressing head is fixed at the front end of the compressing rod and is vertical to the upper end face of the V-shaped block. The standard component is used for initializing the positions of the dial indicator and the compressing head. After the standard component initializes the positions of the dial indicator and the compressing head, the standard component is taken away, a workpiece to be measured is put into the groove position measuring instrument and then the groove position measuring instrument can rapidly and accurately measure the position size of a groove of a bearing core shaft and jerk value of the groove relative to the end face of the core shaft.

Description

A kind of ditch position measuring instrument

Technical field

The utility model relates to a kind of ditch position measuring instrument.

Background technology

The raceway groove position dimension of water pump bearing mandrel and raceway groove require comparatively strict with respect to the jerk value of mandrel section, and the mandrel raceway groove is circular shape, and existing survey instrument can't accurately be measured this size, and efficient is lower.Therefore, need a kind of ditch of design position measuring instrument, so that measure the ditch position dimension of bearing mandrel and raceway groove jerk value in process of production rapidly and accurately with respect to the mandrel end face.

The utility model content

The purpose of this utility model is to provide a kind of ditch position measuring instrument.

The technical scheme that realizes the utility model purpose is: a kind of ditch position measuring instrument, comprise V-block, dial gauge, gauge stand, connecting link, compressor arm, hold-down head and standard component, the left surface of described V-block is provided with vertical dovetail groove, rear end face is provided with horizontal dovetail groove, vertical dovetail groove of gauge stand and V-block is slidingly connected, dial gauge is fixed on the gauge stand, and the left side of vertical V-block, the horizontal dovetail groove of connecting link and V-block is slidingly connected, compressor arm is fixed on the upper end of connecting link, and the rear end face of vertical V-block, hold-down head is fixed on the front end of compressor arm, and the upper surface of vertical V-block; Described standard component is used for the position of initialization dial gauge and hold-down head.

Be equipped with locking device on described gauge stand and the connecting link.

The utlity model has following beneficial effect: vertical dovetail groove of (1) gauge stand of the present utility model and V-block is slidingly connected, the horizontal dovetail groove of connecting link and V-block is slidingly connected, standard component is used for the position of initialization dial gauge and hold-down head, this structure makes standard component behind the position of initialization dial gauge and hold-down head, take away standard component, put into measured workpiece, just can measure the ditch position dimension of bearing mandrel and raceway groove jerk value rapidly and accurately with respect to the mandrel end face.

(2) be equipped with locking device on gauge stand of the present utility model and the connecting link, this structure makes standard component behind the position of initialization dial gauge and hold-down head, and locking device can be locked the initial position of gauge stand and connecting link, improves the precision of measuring.

Embodiment

(embodiment 1)

See Fig. 1 and Fig. 2, present embodiment comprises V-block 1, dial gauge 2, gauge stand 3, connecting link 4, compressor arm 5, hold-down head 6 and standard component 7.

The left surface of V-block 1 is provided with vertical dovetail groove 11, rear end face is provided with horizontal dovetail groove 12, gauge stand 3 is slidingly connected with vertical dovetail groove 11 of V-block 1, dial gauge 2 is fixed on the gauge stand 3, and the left side of vertical V-block 1, and connecting link 4 is slidingly connected with the horizontal dovetail groove 12 of V-block 1, compressor arm 5 is fixed on the upper end of connecting link 4, and the rear end face of vertical V-block 1, hold-down head 6 is fixed on the front end of compressor arm 5, and the upper surface of vertical V-block 1; Standard component 7 is used for the position of initialization dial gauge 2 and hold-down head 6, is equipped with locking device on gauge stand 3 and the connecting link 4.

The gauge stand of regulating on the V-block 1 during measurement 3 makes the gauge head of dial gauge 2 be positioned at the about 20mm of the end face place of V-block 1, then standard component 7 is put into the gauge head that a end that V-block 1 makes standard component 7 withstands dial gauge 2, regulate the height of gauge stand 3 once more, make 3/4 place of measuring point alignment criteria part 7 end faces of dial gauge 2, the locking device envoy gauge stand of regulating then on the gauge stand 33 is fixing with V-block 1, regulate the relative position of connecting link 4 on V-block 1 then, moving compressor arm 5 then downwards makes hold-down head 6 compress the raceway groove of standard component 7, transfer the locking device on the connecting link 4 to make connecting link 4 fixing then with V-block 1, and the pointer of dial gauge 2 is transferred to zero-bit, taking off standard component 7 then puts into measured workpiece on the V-block 1, left hand is held compressor arm 5, the right hand is held measured workpiece, the relative position of regulating the right-hand man is pressed in the raceway groove of measured workpiece hold-down head 6, evenly firmly, compresses measured workpiece, right hand rotation measured workpiece just can read the numerical value that needs this moment.
